The class measured the density of a copper block to be 8.6 +/-0.2 g/cm3 at the 95% confidence interval with a standard deviation
mezya [45]

Answer: kindly check explanation

Explanation:

Given the following :

Measured density of copper block:

8.6+/-0.2 g/cm3

True density = 8.96g/cm3

Standard deviation = 0.4g/cm

a. What is the high and low number of the confidence interval range?

High : 8.6 + 0.2 g/cm3 = 8.8g/cm³

Low : 8.6 - 0.2 g/cm3 = 8.4g/cm³

Does the true value fall within the confidence interval? NO

Actual density = 8.96g/cm³ doses not lie in between (8.4 - 8.8)g/cm³

B.) High and low of the standard deviation range?

High = 8.6 + 0.4 = 9.0g/cm³

Low = 8.6 - 0.4 = 8.2g/cm³

Value falls within range of the true density value of copper block.

8.96g/cm³ falls in-between (8.2-9.0)g/cm³

How many moles of hydrogen gas would be needed to react with excess carbon dioxide to produce 88.1 molesmoles of water vapor?
irga5000 [103]

Answer:

88.1 moles of H₂

Explanation:

Let's make the reaction:

H₂(g) + CO₂(g) → H₂O(g) + CO(g)

Ratio is 1:1

Therefore, 1 mol of hydrogen reacts with 1 mol of carbon dioxide to produce 1 mol of water and 1 mol of carbon monoxide.

In conclusion, 88.1 moles of water must be produced by 88.1 moles of H₂

The reaction can also be written as an equilbrium

H₂(g) + CO₂(g) ⇄ H₂O(g) + CO(g)           Kc
